ASP.NET Core and Vue.js

Overview of this book

Vue.js 3 is faster and smaller than the previous version, and TypeScript’s full support out of the box makes it a more maintainable and easier-to-use version of Vue.js. Then, there's ASP.NET Core 5, which is the fastest .NET web framework today. Together, Vue.js for the frontend and ASP.NET Core 5 for the backend make a powerful combination. This book follows a hands-on approach to implementing practical methodologies for building robust applications using ASP.NET Core 5 and Vue.js 3. The topics here are not deep dive and the book is intended for busy .NET developers who have limited time and want a quick implementation of a clean architecture with popular libraries. You’ll start by setting up your web app’s backend, guided by clean architecture, command query responsibility segregation (CQRS), mediator pattern, and Entity Framework Core 5. The book then shows you how to build the frontend application using best practices, state management with Vuex, Vuetify UI component libraries, Vuelidate for input validations, lazy loading with Vue Router, and JWT authentication. Later, you’ll focus on testing and deployment. All the tutorials in this book support Windows 10, macOS, and Linux users. By the end of this book, you’ll be able to build an enterprise full-stack web app, use the most common npm packages for Vue.js and NuGet packages for ASP.NET Core, and deploy Vue.js and ASP.NET Core to Azure App Service using GitHub Actions.

Installing an input validation library

A user-friendly validation informs the user why the field is not valid while typing the input. We can build it from scratch by writing a validator in every field of the form and making sure that the validators are reactive. The implementation is doable, but it will require a lot of time, and the cleanliness of the code will depend on the developer.

So why not use a library that validates us? Fortunately, there are several Vue.js libraries for validation, and in this section, we will use one of the top libraries.

So let's install an input validation library:

npm i vuelidate

The vuelidate library is a simple lightweight model-based validation that we can use for our Vue application.

Now, let's create a JavaScript file called vuelidate.js in the src/plugins folder and apply the following code:

import Vue from "vue";
import Vuelidate from "vuelidate";
Vue.use(Vuelidate);

The preceding code imports...
